Which subatomic particle can be found revolving around the nucleus?
proton
neutron
electron
Answers
Answer : The correct option is, electron.
Explanation :
As we know that,
An atom is the smallest unit of a matter that consist of three subatomic particles which are electrons, protons and neutrons.
The protons and the neutrons are located inside the nucleus or the center of the nucleus where the mass of the an atom is concentrated.
The electrons are located around the nucleus.
The protons are positively charged, the electrons are negatively charged and the neutrons are neutral that means it has no charge.
According to the question, the electron subatomic particle found revolving around the nucleus.
Hence, the correct option is electron.

for the plant? Use details to support your answer.
Answers
Answer:
Advantage and disadvantage of asexual reproduction in plant is described below in details.
Explanation:
An advantage of asexual reproduction is that the resulting plant will approach adulthood quicker. Since the new plant is emerging from a grown-up plant or plant components, it will also be stronger than a seed. Asexual reproduction can take a spot by natural or manufactured (assisted by humans) means.
The significant disadvantages of asexual reproduction are the Shortage of diversity. Following the seeds are genetically the same as the parent they are more sensitive to the same diseases and nutrient insufficiencies as the parent. All the negative deviations endure for generations.

B) must be available for workers to review
C)are expired if they are more than 5 years old
D )both a and be
E) both b and c
Answers
Answer: B) must be available for workers to review
Explanation:
WHMIS is a Canadian program which gives information to the employers about the workers knowledge about hazardous materials that are used in the workplace. It is ensured that the worker labelled the hazardous material at the workplace, material safety data sheet should be created to supplement the label, and worker's education program for learning the safety precautions is also conducted.
The material safety data sheets are created by the employers and their is no expiry date for such data for workers instead they receive a next recommended training date for participating in the training and avail another certification after the completion of first year.

How is a carbon atom different from a hydrogen atom?
Answers
Answer:
Carbon atom is a chemical element with the symbol C and atomic number 6 ( electrons). While Hydrogen atom is an atom of the chemical element hydrogen that have only 1 electron.
Explanation:
The carbon atom different from a hydrogen atom, because the atomic number of hydrogen is 1 . The atomic mass number of hydrogen is also one. For the carbon atom, the atomic number is 6, and the atomic mass number of carbon is 12.
What is an atomic number ?The term atomic number is defined as the number of a chemical element in the periodic system. The elements are arranged in order of increasing number of protons in the nucleus.
The atomic number is situated at the upper left, or number of protons. In the middle is the letter symbol for the element. Atomic number is equal to the proton number or the number of protons found in the nucleus of every atom of that element.
Thus, Carbon atom is a chemical element with the symbol C and atomic number 6. Whereas hydrogen atom is an atom of the chemical element hydrogen that have only 1 electron and its symbol is H.

What happens when liquid changes to gas?
1.Added heat makes water molecules move fast enough to overcome the attraction
between them
2. Heat causes molecules to speed up and merge together (Which one?)
Answers
Answer:
#1
The temperature that this happens is called the freezing point and is the same temperature as the melting point. As more energy is put into the system, the water heats up, the molecules begin moving faster and faster until there is finally enough energy in the system to totally overcome the attractive forces.
Explanation:
#2
Heating a liquid increases the speed of the molecules. An increase in the speed of the molecules competes with the attraction between molecules and causes molecules to move a little further apart. ... A decrease in the speed of the molecules allows the attractions between molecules to bring them a little closer together.
Apart from cost, give three reasons why steel should be recycled
Answers
Answer:
Well, acutally it shouldnt..but why it should be recycled is because 1. you can use it for many nessactities such as cars and blades, and bikes
You should also recycle it for, scrap parts! so just in case if you need recycled steel ya know where to get it
Lastly, you should recycle steel because of its value. If you recycle steel then melt it, and make well i dont know, a blade out it, you might have just made something, and then think, "Well that was fun and easy, i wanna use more recycled items to build or forge things

Order the following atoms from smallest to largest atomic radius: C, N, P
Answers
Answer:
N ∠ C ∠ P
Explanation:
Atomic radius:
It is define as the distance from nucleus of an atom the outer most electronic shell.
As we move down the group atomic radii increased because of increase of atomic number. Electrons are added in next level cause the atomic radii to increased. The hold of nucleus on valance shell become weaker because of shielding of electrons thus size of atom increased.
When we move from left to right across the periodic table electron are added in the same shell at the same time protons are also added in the nucleus hence positive charge is going to increase and this effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus and atomic radii decreases.
Carbon and nitrogen are present in period 2 while phosphorus is present in period 3 thus phosphorus has largest atomic radii. Carbon and nitrogen are present in same period but nitrogen is more right as compared to the carbon which means nitrogen has one more valence electron thus its size is smaller than carbon.
Values of atomic radii.
P = 98pm
C = 67pm
N = 65 pm

When placed in distilled water, the pH of metal oxides will be?
Less than 7
Equal to 7
greater than 7
neutral
Answers
When placed in distilled water, the pH of metal oxides will be greater than 7. The correct option is C.
What are metal oxides?Metal oxides are crystalline solids containing both a metal cation and an oxide anion. In most cases, they react with water to form bases or with acids to form salts.
Metal oxides are compounds that contain two elements, namely a metal and an oxygen atom. Examples include sodium oxide (Na2O), magnesium oxide (MgO), calcium oxide (CaO), and others.
When metal oxides react with dilute acids, they form salt and water, demonstrating that they are basic.
Metal oxides are alkaline. When we dissolve them in water, we get solutions with pH values higher than 7. The reaction between a nonmetal and oxygen produces nonmetal oxides. Nonmetal oxides are highly acidic.
Thus, the correct option is C.
